Coronary calcium scanning in geriatric cardiology

Coronary artery disease (CAD) is prevalent in the elderly, often leads to disability, and is the number one cause of death in this population. Older adults represent an increasingly important and challenging subset of the population with CAD. They are more likely to have comorbid conditions, atypical presentations, and unfavorable outcomes than their younger counterparts. The available data suggest that standard pharmacologic, thrombolytic, and definitive revascularization techniques have important roles in the treatment of geriatric patients but have been underutilized. Consequently, strategies for optimizing the prevention and treatment of CAD in the elderly are important from both the individual and societal perspectives. Coronary artery calcium has been shown to be highly specific for atherosclerosis, occurring only in the intima of the coronary arteries. There is evidence to show that elevated coronary calcium scores are predictive of future cardiovascular events, both independently of and incrementally to conventional cardiovascular risk factors. This article will review such a screening method, namely coronary calcium scanning, in the field of geriatric cardiology.
